[PATCH] sys_get_thread_area does not clear the returned argument
sys_get_thread_area does not memset to 0 its struct user_desc info before
copying it to user space... since sizeof(struct user_desc) is 16 while the
actual datas which are filled are only 12 bytes + 9 bits (across the
bitfields), there is a (small) information leak.
